It’s getting simpler and cheaper to chill out: US scientists have developed an ultra-cool white paint that can reflect more than 95% of the sun’s rays and keep the house cooler on the hottest days. Across the Pacific in Singapore, researchers have developed a “smart window” clever enough to block the incoming sunlight and regulate the building’s internal temperature. It’s pretty good at blocking the noise from the streets, too.
It’s not just your storage unit that’s packed to the gills. According to a new study, the mass of all our stuff—buildings, roads, cars, and everything else we manufacture—now exceeds the weight of all living things on the planet. And the amount of new material added every week equals the total weight of Earth’s nearly 8 billion people.
